Re: STFM case remake

Hows this project coming along? The 3-D files are still being worked on as mentioned previously somewhere. It will take some time to correct everything and do modifications. But it is still being worked on, but of course we all have day jobs,so time is limited. In the mean time is, especially with ...

Re: STE V1.5 32MHz BOOSTER - STATUS

So today I found a odd issue.. I have seen it before, but I put it down to the previous problems but this seems to be a new problem, it is difficult to tell if there is still a bad connection or not.. I'm not sure if the board I was testing yesterday and this issue or not, but I will retest later to...

Re: My latest restoration in pictures

Think this was all going on early 2000. Thought the bad cap thing was earlier than that, more like early 90s ? Never looked into it.

EDIT:
Oh found it... https://en.wikipedia.org/wiki/Capacitor_plague

Probably explains what I saw in my old job then.

Re: My latest restoration in pictures

Caps in ST are not known to cause problems or being excessively faulty. That is simply not true, I documented it like 10+ years ago that PSU's were failing in STEs. I even documented why on my site. Bad caps. I've had like 200 PSU's through my workshop, none of which will power a STE with 4MB RAM (...

Re: STE V1.5 32MHz BOOSTER - STATUS

So this one worked first time.. see how it goes.. got the new firmware in it...

It it seems OK, will sell it cheaper for someone to beta test it ;) Will have a second one when I get more bits..

Re: no-software internal RTC

:bravo:

Have you talked to Jookie about this stuff ? He did a keyboard injector for cosmosex and may be able to give some more info on it all.

Re: STE V1.5 32MHz BOOSTER - STATUS

It does not look like a real-time 8MHz switch will be possible with this design. There simply isn't enough IO power in that PLD :( Problem is I have to delay DTACK because the CPU is running faster. Though I also have to turn this delay off to get back to stock 8MHz speeds. The problem is when the s...

Re: STE V1.5 32MHz BOOSTER - STATUS

Board is getting there :)

I just tested the 8MHz switch and while it works, it actually glitches during transition :roll: I think it is a problem with my wait state code.. So currently sidetracked while I investigate the issue...

Re: STE V1.5 32MHz BOOSTER - STATUS

What I will try today is pre-soldering the CPU pins on the PCB as shown below.. Then I will paste the whole board and assemble.. This way the CPU pins have double the amount of solder on them..
